FS20083 Fuel Water Separator — DAVCO Fuel Pro 485/487/488, DD13/15/16, ISX

The FS20083 is a high-performance fuel/water separator cartridge built with Fleetguard EleMax StrataPore multi-layer coalescing media. Sized as the standard-length element for DAVCO Fuel Pro 485, 487, and 488 fuel processors, it delivers class-leading water separation and fine-particulate capture across Cummins ISX, Detroit DD13/15/16, and Navistar A26 platforms.

Key Features

• EleMax three-stage architecture — coalescer, hydrophobic barrier, and polishing stage
• 100% free-water removal and up to 90% emulsified-water separation
• StrataPore media rated for 10 microns with high dirt-holding capacity
• Built-in bypass valve ensures uninterrupted fuel flow under extreme pressure differential
• 8.99" height × 6.08" OD — drop-in replacement for DAVCO Fuel Pro 485/487/488 housings
• Biodiesel compatible — safe for modern blended fuels

Why Water Separation Matters

Water is the number-one contaminant in diesel fuel. It accelerates corrosion inside pumps and injectors, promotes microbial growth that plugs filters, and causes cavitation damage in high-pressure common rail systems. The FS20083 actively coalesces and drops out emulsified water into the collection bowl of your DAVCO processor before it can reach the engine — dramatically reducing the risk of costly fuel-system failures.

Application & Fitment

• DAVCO Fuel Pro 485, 487, and 488 fuel processors
